Description
The Bently Nevada 330730-080-01-00 is an 8.0-meter (26.2 feet) extension cable designed for the 3300 XL 11 mm Proximity Transducer System. This cable is a critical link between the proximity probe and the Proximitor sensor, facilitating non-contacting vibration and displacement measurements on fluid-film bearing machines. The 11 mm system is specifically engineered for applications requiring a longer linear range, such as axial (thrust) position monitoring.
Features
- Compatible with 3300 XL 11 mm Proximity Transducer Systems.
- Armored cable construction for enhanced mechanical protection in harsh industrial environments.
- Standard 8.0-meter length.
- Designed for high-reliability signal transmission in rotating machinery monitoring.
- Maintains system linear range of approximately 4.0 mm (160 mils).
Applications
- Oil & Gas Refineries and Petrochemical Plants: Monitoring compressors, pumps, and fluid-film bearings.
- Power Generation: Axial and radial vibration monitoring for turbines (hydro, coal, combined-cycle).
- Mining and Metal Processing: Heavy equipment monitoring such as ball mills and crushers.
- Water and Wastewater Treatment: Critical pump and blower monitoring.

Installation Guidelines
- Ensure all system components (probe, extension cable, and Proximitor) are matched 3300 XL 11 mm series parts to maintain calibration accuracy.
- Use ClickLoc connectors to secure the cable between the probe and the Proximitor.
- Connector protectors are highly recommended to prevent moisture and contaminant ingress in humid or dirty environments.
- Ensure the armored cable is routed away from high-voltage lines to minimize potential EMI interference.
- Always power down the monitoring system before disconnecting or connecting transducer cables.
FAQ
What is the primary purpose of this cable?
This cable connects the 11 mm proximity probe to the Proximitor sensor, allowing the system to measure vibration and position on fluid-film bearing machinery.
Is this cable suitable for harsh environments?
Yes, the 01 option indicates an armored cable design, which provides superior protection against mechanical damage in industrial settings.
Can this be used with 8 mm probes?
No, the 3300 XL 11 mm system is designed specifically for 11 mm probes. Mixing components from different series will result in inaccurate measurements.
